Measure real-time cAMP signaling kinetics in the primary cilia with this live cell fluorescent assay. Add 5HT6-tagged cADDis to your cells and measure robust signals the next day on a fluorescence imaging system. Decreasing green fluorescence indicates ciliary cAMP increase. Constitutively expressed cytosolic red fluorescence can be used for ratiometric measurements. This assay is genetically encoded and packaged in BacMam for efficient transduction in most cell types - including uniform and near 100% efficiency in HEK293 cells as well as expression in many primary or iPSC-derived cells. The kit includes the cilia-targeted cAMP sensor BacMam and 500mM sodium butyrate in H2O. 10mL size is available as well.
